First I'd like to say "NO. STOP. SHUT UP." on the fact that making any complaints about ME 3 at this point is sooooooo two months ago.
But we're here anyways, right? Might as well go down the list.
1: People had been requesting ME multiplayer since the first game, they were REALLY wanting a co-op campaign. Well Shepard works "alone" in the sense that no one's as badass as him/her. And as much as everyone would love to play 2nd player as Garrus, it just wouldn't be the same. As such, the multiplayer which effects the campaign is a decent middle-ground between having multiplayer that's utterly disconnect and a full-fledged co-op campaign.
2: I'll give you this one...ME 1's quest tracking was the best, each quest would update and specifically say "You've already been to this place in this system, now you have to go to this place in this system. All done? Well you're ready to go back to the Citadel and turn it in." Now we just get some BS list that just mentions "Some guy needs something. Go find it. NO! We're most certainly NOT going to tell you whether or not you found it in that last round of scanning!"
That and I don't like how the quest log ALWAYS jumps 2/3 of the way down into the "already completed" section, making you scroll back to the top to find what you still have to do...incidentally I also don't like how the weapon upgrade menu jumps back to the top after each upgrade you purchase...
3: Hasn't happened to me very often...every now and then, though an engineer my place a "cloaked" turret which can be rather annoying. But in many cases it seems like an animation glitch prevents someone from standing up or moving to where they're supposed to be so that when the camera cuts over to where they SHOULD be they're still where they were.

Just saying technically, at least in my experience, people don't actually go invisible.
4: Another nit-pick if you ask me. It didn't take more than two or three tweaks to get my imported face from "wtf is this?" back to "That's how it's supposed to look." But then again I'm not OCD about having to mess with EVERY SINGLE CATEGORY in the face customization. I normally just mess with the eye color, maybe change the eyebrows, pick myself some hair and hair color, if I'm making a FemShep I'll give her some lipstick and eye shadow, then the character is good to go.
5: Ehhhh, yeah, I was kinda disappointed with the way the Rachni situation ended. Personally - even though I knew it was a pipe dream - I was hoping you'd get a rachni squadmate! Somethign like the dog character from Dragon Age: Origins. I do agree that it seemed like a pretty big cop-out to have them present even if you DID kill the queen in ME 1, but at the same time that'd remove a rather massive threat from the Reaper forces. Then there's the fact that Samara quite clearly states in ME 2: "There are three Ardat-Yacshis (or however it's spelled) in existence...and I have three daughters...it is as it seems." So where are all these damn banshees coming from? But I've let bigger transgressions slide by with the suspension of disbelief. Is it a cop-out in both cases? Yeah, but I'd hardly consider either an experience-ruining defect with the game.
6: Liara actually explains this: "Process of elimination combined with desperation. You've got a massive harddrive filled with tons of data in languages and formats that have been extinct for 50K years...I highly doubt finding the crucible plans would be as easy as saying "Computer, show me some massive weapon schematics." Take it as Serendipity revealing the plans when the galaxy needed them most.
7: Soooooo what, you were wanting the entire cast from ME 2 to be back on the Normandy?
Well aside from the fact that Shepard was relieved of duty and placed under house arrest for a few months being good reason for everyone to scatter from the Normandy, each has their own justifiable reason for not being able to come back.
<spoiler=ME 2 Characters and Why They Cannot Come With You>Jacob: No one misses him, be honest, not even you. So no one cares that he's now wanting to start a life for himself.
Samara: She says herself, in a time of war the Code demands that she goes to where the fighting is most dire, and that is not on the Normandy.
Miranda: She's obsessed with her father and sister, as she always is, and cannot abandon her search for her sister.
Jack: Having learned a thing or two about teamwork and responsibility by joining Shepard's suicide squad, Jack is now a teacher of biotic students. Given her own past, she has become extremely attached to the kids and will not abandon them.
Legion: He returned to the Geth consensus to ensure that they would be ready for the Reapers when they returned. The Geth were subsequently pinned into a war with the Quarians.
Kasumi: Really I never understood why she was in ME 2 to begin with...she's a thief, not a fighter. Which is exactly what she tells you when you start thinking about inviting her to join you in ME 3.
Thane: Too sick to help this time around.
Zaaed: No real reason that he couldn't have joined back up with the main force, I'll admit, other than maybe he's helping to coordinate the mercs that you pick up.
Morinth: She's a wanted murder in countless systems...wouldn't really be wise for Shepard cruising around with her.
Mordin: Felt guilty about his work with the genophage so he wanted to make things right. As such he joined up with the facility working on the Krogan females. You then either shoot him in the back, he makes the noble sacrifice, or you both agree the cure is bad if Reeve is in charge and as such he goes into hiding to avoid retribution.
8: Simple, really, it's the same reason there's no Collectors in ME 3: the Seeker Swarms were all wiped out with the destruction/irradiation of the Collector Base.
As for why conquering Earth took so long? Well as far as I can tell, ME 3 takes place over the course of two or three months. And while it's easy to take out the major cities, hunting through the less populated areas of the planet would take much longer to do a clean-sweep since, as I mentioned, the Collectors and all their tech was wiped out with the Collector Base.

With regards to the Council in ME 2: Yeah, I gotta say I thought it was bullshit how they all went back to denying the existence of the Reapers despite everything that happened in ME 1, so I can't really argue that.
ME 3: Shepard wasn't specifically grounded for the Alpha Relay incident. In fact, if you didn't play that DLC, Shepard wasn't even involved in that incident, it was just a generic Alliance marine team. Shepard was in custody for going completely rogue and AWOL by joining up with Cerberus - a known terrorist group and enemy to all Citadel species - to stop the Collectors. Yes, Shepard was doing it for the right reasons, but that doesn't change the fact that he joined up with Cerberus...which rebuilt him after his death...I think the Alliance's skepticism and mistrust of Shepard upon his/her return is justifiable.
As for the Multiplayer and Squadmates...the squadmates I've already addressed in the above section, the multiplayer unlocking system....ehhh, yeah, the randomness of the unlocking can be a bit frustrating, but I'd hardly call it a major fault. It's clearly a tactic to keep people playing the multiplayer, but at the same time, it does prevent everyone from using the same 3 badass guns and classes right from the get-go. Am I annoyed that I STILL haven't gotten a Geth Infiltrator? Yeah...but there's plenty of other fun classes out there in the mean time.
